Colors SSG4600 UltraGlaze is available in black and medium grey. Black: SSG4600A + SSG4603B Medium Grey: SSG4600A + SSG4607B Limitations Structural glazing industry guidelines (ASTM C1401) suggest that drawings and details are to be reviewed by all parties involved in the manufacture of an SSG system and for each building project. SSG4600 should be used in structural glazing applications only after Momentive Performance Materials (MPM) has reviewed detailed design drawings and has performed adhesion and compatibility tests on project substrates and relevant spacer materials. Review and testing is done on a project-by-project basis. No blanket approval is given by MPM for structural glazing applications. MPM requires testing on a project-by-project basis each substrate and component used in a structural glazing assembly for adhesion and compatibility. No blanket approvals exist relative to adhesion or compatibility of SSG4600 with such materials. Not recommended for water immersion applications. Technical Services Additional technical information and literature may be available from MPM. Laboratory facilities and application engineering are available upon request from MPM. Any technical advice furnished by MPM or any representative of MPM concerning any use or application of any product is believed to be reliable but MPM makes no warranty, express or implied, of suitability for use in any application for which advice is furnished. Applicable Standards SSG4600 meets or exceeds the requirements of the following specifications for two-component sealants.

3 Joint Designs and Dimensions Figure 1: Silicone contact width and thickness (see Figure 1) will vary by project with the design wind load and glass size. Contact width can be calculated using the following formula: CW Contact Width (inches or millimeters) DWL Design Wind Load (pressure in PSF or kpa) LSS Longest Short Span (largest piece of glass; shorter side) SDS Sealant Design Stress: Dynamic (wind) loading: 20 psi (138 kpa) Permanent (dead) loading: 1 psi (7 kpa) CW = DWL (PSF) x LSS (Ft) SDS x 24 STRUCTURAL SILICONE DEPTH (THICKNESS) CONTACT WIDTH CW = DWL (kpa) x LSS (mm) SDS x 2 Alternate calculational methods may also be employed to derive the contact width. In all cases, a minimum safety factor of five (5) is to be used in conjunction with the sealant s ultimate tensile strength suitable in the proposed condtions of applicability. Contact Momentive Technical Services team for review of proposed designs. A minimum sealant thickness of 1 / 4 (6mm) between substrates is required to accommodate thermal expansion and contraction (see Figure 2) of most systems and should be used in order to ensure that sealant can be injected into the structural cavity obtaining full contact with both the glass and metal surfaces while remaining free of voids. Greater joint thickness may be required to accommodate movement in some larger-sized SSG systems. MPM can be contacted to assist in determination of proper joint thickness to accommodate expected movement, in structurally glazed applications.

Surface Preparation Sealants may not adhere or maintain long-term adhesion to substrates if the surface is not prepared and cleaned properly before sealant application. Using proper materials and following prescribed surface preparation and cleaning procedures is vital for sealant adhesion. MPM can provide quality control information and suggestions to users upon request. Materials Use clean, fresh solvent as recommended by the MPM project-specific test report. When handling solvents, refer to manufacturer s MSDS for information on handling, safety and personal protective equipment. Isopropyl Alcohol (IPA) is commonly used and has proven useful for most substrates encountered in SSG systems. Xylene, MEK and Toluene have also been found useful on many substrates. Do not use Denatured Alcohol. Denatured Alcohol is not suggested because of the variability of additives, which may or may not provide reproducible results. Use only clean 99.9% pure industrial grade solvents. Do not use diluted solvents. Use clean, white cloths free of lint or other suitable lint-free wiping materials. Use a clean, narrow-blade tooling knife when tooling structural silicone into the cavity. Use primer when required (reference MPM project-specific adhesion test report (s)). Cleaning Procedures R emove all loose material (such as dirt and dust), plus any oil, frost or other contaminants from the substrates to which the structural silicone will be applied to. Do not use detergent to clean the substrate as residue may be left on the surface. Clean the substrates receiving the sealant as follows: Using a two-rag wipe technique. Wet one rag with solvent and wipe the surface with it, then use the second rag to wipe the wet solvent from the surface BEFORE it evaporates. Allowing solvent to dry on the surface without wiping with a second cloth can negate the entire cleaning procedure because the contaminants may be re-deposited as the solvent dries. Change the cleaning rags frequently, as they become dirty. It is easier to see dirt if white rags are used. Do not dip used wipe cloths into solvent as this can contaminate the solvent. Cleaning with contaminated solvent can result in sealant adhesion issues. Always use clean containers for solvent use and for solvent storage. When cleaning deep, narrow joints, wrap the cleaning cloth around a clean, narrow-blade putty knife. This permits force to be applied to the cleaned surface. Clean only as much area as can be sealed in one hour. If cleaned areas are again exposed to rain or contaminants, the surface must be cleaned again. Primers SSG4600 will bond to many clean surfaces without the aid of a primer. For difficult-to-bond substrates, the use of a primer or special surface preparation should be evaluated. An evaluation should be made for each specific application/substrate to determine quality of bond. When properly used, primers help assure strong and consistent sealant adhesion to surfaces that may be difficult to bond. Most primers are a blend of organic and inorganic chemicals, resins and solvents. NEVER APPLY PRIMER TO GLASS SURFACES OR TO CURED SILICONE RUBBER WITHOUT PRIOR CONSULTATION WITH MOMENTIVE PERFORMANCE MATERIALS TECHNICAL SERVICES. Obtaining the proper materials, as well as following the prescribed procedures, is vital to ensure the successful use of primers. PRIMER APPLICATION IS NOT A SUBSTITUTE FOR SURFACE PREPARATION. Consult primer datasheet(s) for specifics and instructions for use. CAUTION Primers may contain solvents. When handling solvents, refer to manufacturer s MSDS for information on handling, safety and personal protective equipment. Masking To simplify clean up of excess sealant, use easy to release, pressure sensitive tape to mask adjacent surfaces before applying the structural silicone sealant. Start from the top down and overlap the runs. Tool in direction of over-lap so that masking is not disturbed during tooling. Remove masking immediately after application of silicone or as soon as practical. Drop cloths can be used to cover any surfaces likely to collect excess sealant removed during tooling operations. P. 05

6 Sealant Application Apply the sealant by pushing the bead ahead of the nozzle and making sure that the entire cavity is filled. Tooling should be done neatly, forcing the sealant into contact with the sides of the joint, thus helping to eliminate any internal voids and assuring good substrate contact. AIR POCKETS OR VOIDS WITHIN THE STRUCTURAL CAVITY ARE NOT ACCEPTABLE. Sealant application is not recommended when the temperature is below 50 F (10 C) or if frost or moisture is present on the surfaces to be sealed. SSG4600 works best when applied to surfaces below 140 F (60 C). Due to the smooth consistency of SSG4600, tooling agents such as water, soap or detergent solutions are not necessary or recommended. Dry tooling is recommended. Mixing, Pumping and Dispensing SSG4600 should be mixed and dispensed using suitable two-component mixing equipment, available from several equipment manufacturers. These mixing / pumping systems are specifically designed to meter precise proportions of A base and B catalyst, in an air-free environment, and mix and dispense material at proper pressures and volumes to insure thoroughly mixed air-free material. Reference MPM SSG Technical Manual & Quality Control Information document for informatioin regarding suitable equipment type for use with SSG4600. Consult mixing equipment manufacturer or system operating manual for startup and shutdown procedures that cover proper operating pressures, mixing devices, and purging requirements. Hand mixing of A base + B catalyst is not recommended, except for pre-use testing to confirm cure. Kit matching of the A and B components of SSG4600 is not required. SSG4600 can be used successfully in both In-line mixing systems and on purgeless after-the-gun mixing equipment. Consult equipment manufacturer and/or MPM for information on mixing device options. When properly mixed, the material should be a solid, homogeneous color (gray when using SSG4607B catalyst, black when using SSG4603B catalyst) free of any swirling or marbling of colors. If incomplete mixing is noticed, cease use of the material until equipment has been adjusted and confirmed that complete mixing is being attained. Work life and cure rate may be adjusted by changing the A base to B catalyst ratio. Ratio must be within recommended range to achieve desired cured material property profile. Work life and cure rate can be affected by temperature and humidity levels. Mild heat (i.e., around 120 F/49 C) will shorten the work life of the material, but will not significantly reduce the time required for complete cure. Cooler temperatures and lower humidity (i.e, <50 F/10 C and <30% R.H.) tend to slow the cure and adhesion process. The B catalysts are sensitive to prolonged exposure to atmospheric moisture and the storage containers should be kept tightly closed whenever possible to maximize useful life. The catalyst will require mixing before placing container in pumping equipment if settling of components has occurred. Contact MPM technical services for additional information. Adhesion Development of maximum bond strength will depend on substrate finish, joint configuration, primer use, adhesive width, substrate preparation and ambient conditions at location of use. Minimum stress should be applied to the adhesive bond for 24 hours. The adhesive strength of the bond should eventually exceed the cohesive strength of the silicone rubber adhesive. Maintenance and Repairs If repairs are required, the following products are candidates for use: SSG4600, SSG4000, SSG4000AC, SSG4000E, SSG4800J, SCS2000. Reference MPM SSG Technical Manual & Quality Control Information document regarding specific requirements for substrate preparation when reglazing. Curing When mixing SSG4600A base + SSG460XB catalyst at approximately a 12:1 weight ratio, the material will become tack-free after about 1-2 hours under ambient conditions 70 F (21 C), 50% R.H. Under these conditions approximately 70% of strength should develop within 24 hours. Development of full properties requires full liberation of cure by-products and will normally be achieved within 7 days. Full properties will take additional time in colder climates or deeper SSG cavities. P. 06
